| (ii) Stratosphere | 10 to 50 kilometers | The stratosphere contains the ozone layer which prevents the harmful effects of the sun (U. V. rays) from reaching the earth. |
| (iii) Mesosphere | 50 to 80 kilometers | The mesosphere is a very cold layer and most meteors burn up in this layer and hence are prevented from entering the earth's atmosphere |
| Thermosphere | 80 to 320 kilometers | - |
